Oh, I loved the camera. In the corridors it's perfect, and adds a lot of impact to some of the areas.
I don't remember a worm boss. But I already beat the game so I remember lots of bosses
The post-credits stuff is pretty cool, just running around collecting shit. And the whole time I was thinking "you know...it's not a Metroid game unless it has THIS thrown in. Kinda weird that they left it out." Then they totally threw it in at the very end, and I was happy :D
Got 56% on my first run through, which is the EXACT percentage I finish every Metroid with on my first try. It's kind of aggrevating that I never do better on my first go
At least the game lets you load up your finished save and keep collecting.
